| Abstract: |
We discuss the general relativity effects acting on the radiation signal
from the inner accretion flow. We consider the radiation flux and
polarization properties originating from a blob of gas near a rotating
black hole. The predicted observed polarization at infinity is changed
from its local value due to strong gravity and fast orbital motion.
Different processes can produce the observed pattern: in the context of
Sgr A* flares, the synchrotron mechanism and the inverse Compton
up-scattering appear to be the most likely mechanisms. |
